Category: None Group: Python 2.5 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Shane Holloway (shane_holloway) Assigned to: Nobody/Anonymous (nobody) Summary: CTypes _as_parameter_ not working as documented Initial Comment: Reference: http://docs.python.org/dev/lib/ctypes-calling-functions- with-own-custom-data-types.html According to this document, I should be able to use my own objects with ctypes, provided I have an _as_parameter_ attribute set on my object. However, this does not work properly when the foreign function's argtypes have been set. This is because the _as_parameter_ access is not done until after the argument types are checked. Attached is a patch that adds _as_parameter_ checking to the types provided by _ctypes.c so that the feature works as documented for both typed and untyped foreign functions.
